Awesome! I recently fell in love with Burn Notice, and I haven't seen Charisma in anything since Veronica Mars.

It seems like shows like Burn Notice and Leverage have a cult following similar to a lot of genre shows. These shows are like Angel without the demons, complete with a quirky, lovable team. Maybe that's what attracts genre actors. And then some of the casting directors other credits include genre shows like Moonlight, Drive, Nikita, & V.

On a side note, in an interview with Deadline, Matt Nix (the creator of Burn Notice) was asked to talk about how a lot of showrunners are now interacting directly with there fans online and he responded with:

"All of us owe a lot to granddaddy Joss Whedon [Buffy the Vampire Slayer, Dollhouse], who was out there on that."

Well Matt Nix only needs to look at Bruce Campbell (the 2nd banana on Burn Notice and on Xena) for a cult hero who knows how to stay in touch with his fans (Burn Notice will not be represented at Comic Con, but Bruce will be there). They've hired a lot of genre actors, but I thought a lot of that was because of Bruce Campbell.
